[Solved] Sound1 is not a valid member of PlayerGui ?

Here's the script : it is placed in an union in Workspace.

script.Parent.Touched:connect(function(hit)
    if hit.Parent:FindFirstChild("Humanoid") and game.Players[hit.Parent.Name].PlayerGui.Sound1.IsPlaying==false then
        game.Players[hit.Parent.Name].PlayerGui.Sound1:Play()
    end
    if hit.Parent:FindFirstChild("Humanoid") and game.Players[hit.Parent.Name].PlayerGui.Sound2.IsPlaying==true then
        game.Players[hit.Parent.Name].PlayerGui.Sound2:Stop()
    end
end)

Studio Play & Play Here : works Local Server | 1 Player : does not works InGame Does not works

With a output script I managed to see this : Sound1 is not a valid member of PlayerGui

BTW : before doing an anti virus scan and removing models in my game : the script above was entirely replaced by :

69

Now it no longer does it.
